To all whom it may concern:

Be it known that I, GEORGE W. BAKER, a citizen of the United States, and a resident of Wilmington, in the county of Newcastle and State of Delaware, have made a certain new and useful Invention in Machines for Fleshing and Working Out Hides and Skins; and I declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it appertains to make and use the invention, reference being had to the accompanying drawings, and to letters and figures of reference marked thereon, which form a part of this specification.

Figure 1 is a perspective view of my ma chine. Fig. 2 is an end elevation of the same.

Fig. 3 is an elevation of the opposite end of Fig. 4 is a cross-section of the upper part of the machine. Fig. 5 is a detail view of gears 18, 19, and 20. Fig. 6 is a detail view illustrating the clutch p and its connections. Fig. 7 is a detail section on the line 7 7, Fig. 2. Figs. 8 and 9 are detail views.

The invention relates mainly to roller-machines for fleshing hides and skins and it consists in the novel construction and. combinations of parts, as hereinafter set forth.

Hides and skins before being made into leather have the surplus flesh removed. In some cases this is done before the hair is taken off and sometimes after the hair has been removed. In the former case the operation is called. green fleshing. In the latter case it is called .lime fleshing, because it is done after the skins have been treated with lime to allow the hair to come out freely.

In the accompanying drawings, illustrating the invention, the letter a designates the end supporting-frames, which are provided with suitable longitudinal bearingbars. these supporting-frames are secured the upper frames 1), which carry the chief mechanismthat is to say, the cutter-roll c, the corrugated feed-rolls (Z and 7', andv the rubbercovered bed-roll c, with their connections. On the main frame is mounted the crankshaft f, carrying a spur-wheel g, arranged to operate in connection with suitable stopping and starting mechanism. Below the crankshaft is located a shaft 71 carrying a large chain gear-wheel 7c and a loose pinion m, which engages the spur-wheel g. On the hub of the pinion is fastened one part a of a frictional clutch 1:, said part having an interthe machine.

Upon a top roller shaft.

nally-tapering wood filling 1', with which the other or sliding part 8 of the clutch-engages, this being driven by a feathered key on the end. of the shaft.

On a shaft u, extending at right angles to the clutch-shaft, is provided an arm 17, which engages the groove to of the hub of the part a of the clutch. On this pivot-shaft u of the an lo-lever is loosely mounted a trip-arm or rol er-arm 2, this arm being adjusted by means of a double-fingered driver 2, which is keyed to the shaft u. Adjusting set-screws 3 are provided to regulate the trip-arm in relation to the cams 8, placed diametrically opposite each other on the main crank-wheel g, and to provide for such compensation as may be needed by the wear of the friction-cams. At the end of this pivot-shaft u is secured an arm 4, having a counterweight t, which is designed to operate in an automatic manner to hold the clutch in engagement with. sufficient friction to revolve the cranks 5 and operate the side link-bars 6 and mechanism in connection with the bed-roll c, on which the hide is worked. This operation is stopped intermittently and automatically by the action of the trip-arm z and stop-cams of the spurwheel g.

At the rear end top of the machine is mounted in bearings 9 a stationary shaft 10, to which is pivoted the hinged yoke-frame 11, carrying the feed-rolls. On this shaft 10 at the end is located the feed-pulley 12, having a long hub, to which is secured a pinion 13 and a chain gearwheel 14. The pinion 13 engages a toothed wheel 15 on the shaft 16 of the upper feed-roll, and the chainwheel 14 drives the shaft h, which carries the clutch devices, by engagement of its chain with the wheel is. The second or lower feedroll is located midway between the top feedroll and the cutting-cylinder and is supported in bearings of the hinged frame, these bearings being the hubs or boxings in which the journals of the upper feed-roll are seated. These two feed-rolls are in engagement by their gear-wheels18 and 19 and an intermediate wheel or idler 20, which is of double their width and is driven by the wheel 18 of the Spring compression devices are provided in front at 21 and in rear at 22 of the feed-roll frames, being designed to hold the rolls firmly yet yieldingly in contact with the hide, so that there will be compensation for varying thicknesses of the hide passing between them and the bed-roll.

IIO

23 indicates a treadle projecting in front and secured to a shaft 24, on which is keyed a shaft-arm 25, to the end of which is jointed .a long arm 26, extending obliquely to within a short distance of a round projection 27 on the inside of the crank gear-wheel. There are two of these projections diametrically opposite to each other, and at each half-revolution of the wheel they are operated by the arm 26 to push the wheel forward and past one of the cam stop devices, thereby allowing the weighted arm to fall and move the clutch into working position, rotating the wheel one-half revolution or until the opposite stop-cam has moved to the roller-arm that trips the clutch out of gear. In other words, pressure on the treadle serves to push the wheel over the dead-centers, allowing the weighted arm to fall, operating the projecting part of the clutch to slide into engagement with the recessed part. Every time the treadle is pressed the cranks make a half-revolution and the bed-roll is moved into or out from the cutter-cylinder.

Pivoted at the lower portion of the frame at the ends are the upright arms 28, which carry at their upper ends means of adjustment to compensate for wear of the cuttercylinder and to provide for changing the distance of the bed-roll from the cutter in accordance with the different kinds of work to be performed. The upper ends of the upright pivoted arms 28 are each forked and provided with bearings for the journals of a pivoted nut 29, which receives a large screw 30, which is provided with handles and with a jam-nut 31, also provided with handles. This large screw 30 is provided with a longitudinal perforation or bore to receive loosely a long stem 32, the inner end of which is connected to a yoke or sliding bearing 7, seated in horizontal ways 35 of the frame and carrying the journals of the bed roll. On the threaded end of the stem are placed jam-nuts to hold it to its adjustment. Around each stem 32 is placed a compensation-spring 33, one end of which bears against the trunnioned nut and the other end against thebearing or yoke 7.

The rubber or bed roll is provided with a gear-wheel 40, having long teeth and designed to engage a gear-wheel 41, also having long teeth and attached to the shaft of the top feed-roll. These operate for driving engagement andare also designed to compensate for the different thicknesses of the hide being worked as well as for any wear on the rubber roll. At the back of the frame is lo cated on each side in connection with a bearing at the rear end of the horizontal slideway 35 an adjustable stop-screw 36, against which the bearing or boxing of the bed-roll is designed to bear when moved into engagement position. The gear-wheel 41 on the feed-roll is mounted loosely on its shaft, but is pro vided with a fiange 37, having a tooth 38, adapted to engage a corresponding tooth 39, fixed on the shaft. The driving engagement is effected when these teeth come together, and the play is designed to decrease the shock of engagement when the bed-roll is pulled into engagement by means of the side cranks.

In the operation of the machine a hide is laid over the rubber roll, with about twothirds of its length hanging. The treadle is pressed and by means of its connecting mechanism moves the gear to which the cranks are attached far enough around for the trip-arm to clear itself of the cam-stop. The weighted arm at the same time brings the clutch into action, and the cranks commence to rotate one-half revolution, carrying the bedroll, with the hide, to the cutter-cylinder and causing the long-tooth wheels to engage, then turning in a direction to feed the hide toward the operator. When part of the hide is finished, the treadle is again pressed, bringing the bed-roll to the front again, and then the hide is turned end for end and the unfinished portion put through the same operation.

The machine is designed to be driven by two belts from the same shaft, one driving the cutter and the other the feed-pulley.
